More Information
Summary:A multilayer filter includes a laminate including a plurality of dielectric layers stacked on each other. Inner layer electrodes and outer terminals are provided in the laminate. A second coil electrode constituting a balanced-side inductor is defined by one of the inner layer electrodes. The second coil electrode has a coiled shape, and includes a first end connected to a first coil electrode through a via electrode and a second end connected to a third coil electrode through a via electrode. The second coil electrode is connected at a predetermined position along the winding direction thereof to a ground terminal, as one of the outer terminals, through an electrode for connection to a ground. The position where the ground connection electrode is connected to the second coil electrode is determined based on a balance characteristic in the balanced terminal side.
